IR Remote and Use
1. Power on or Standby:
Power on the matrix or set it to standby mode.
2. Input 1/2/3/4:
Select input channel.
◄ ►: Select the last or next source.
3. Output 1/2/3/4:
Select output channel.
All: Select all output sources simultaneously. For example:
Press the “All” button and then press input button “1”.
Input “1” source content will be output to all display
devices.
Press the output button first and then press the input button to select the corresponding
input source. The matrix can select the input and output source via the IR remote. There are
two ways to receive the IR remote signal.
Direct: The IR window on the LED display will receive the remote signal at a distance of up
to 8 meters when the IR remote is directly facing the matrix or 5 meters when at an angle of
± 45°.
IR Extension: If the IR receiver window of the matrix is blocked or the Matrix is installed in
a closed area out of infrared line of sight, the IR receiver extension cable can be inserted to
the “IR EXT” port to receive the IR remote signal. The furthest distance when using the IR
remote and extension cable is 5 meters when directly facing the IR receiver extension and 3
meters when the angle is ± 45°.

Web GUI User Guide
The BG-8K-88MA can be controlled via the built-in Web GUI as shown below.
Step 1: Obtain the current IP Address of the matrix.
The default IP address is 192.168.1.100.
Users can get the current IP address in two ways:
1: View the IP address via the panel buttons. On the initial OLED display, press the “MENU”
button to enter the IP interface and then press “UP/DOWN” button to check the current IP
address.
2: Users can get the IP address via RS-232 control. Send the command “r ipconfig!”
